Materials and methods: The pilot study included 17 patients collected between the 12th and the 42nd week of gestation. The TS was measured by a single operator by quantitative elastography. The influence of DP values (5, 10, 15, and 20mm) and phase (compression versus relaxation) was tested after a cycle of freehand compression and relaxation of the cervix through the vaginal probe. Feasibility and intra-operator intraclass correlation coefficient (ICC) agreement for strain measurement were also evaluated for every setting used. Results: TS values were inversely correlated with DP and were slightly higher if measured during a compression phase. TDI-based cervical elastography was feasible in all cases. Reliability for the process of strain calculation of different raw datasets was very good (ICC agreement ranging between 0.79 and 0.87), while excellent considering the same raw dataset (ICC agreement ranging between 0.93 and 0.95). Conclusions: The DP and cycle phase influenced the strain values calculated. Nonetheless, TDI-based cervical elastography was feasible and reliable for all the settings considered.
